/** Defines type of lines of map data.

    Each line of map data consists of 8 TInt16s. The type of each line
    is given by the first.

    If the type is EMapLineBackground then the
    next four TInt16s are the background sprite numbers to be plotted.
    
    If the type is EMapLineObject the a new bad guy is added to the
    array of bad guys (if there is a slot free). The type and 7 TInt16s
    are passed to TBadGuy::Init() which adds the appropriate bad guy.

    If the type is EMapLineEndOfMap then the map stops scrolling and
    no more bad guys are added.

    CMap::ProcessMapLine() processes the map data.
